Though trains coming from BSL side going towards DD do not need reversal at MMR but this train gets a reversal at MMR for faster engine changing process. While the electric engine is being removed at one end other end of the train is prepared to be attached by a diesel engine. The virtual junction at Ankai helps this trains to take DD route. I have posted the rail track diagram of the Manmad area. This train has a reversal at Manmad. Source of reversal info is that I have personally seen this.
